Just replacing rear axle seal. Not sure what floating axle means. Do bearings need packed with grease or does diff. oil lubricate bearings. Also, what axle diff. do I have. Axle code is D1, TR is 6, Spr is XB. Diff. #'s are 6 409 9, or 3L73105 8189. Can you help me with these numbers. Also, the seal exploded and there is a 4 slotted washer that looks like it came out of the seal. Or is it actually a washer that needs to back on axle?

you got a sterling 10.5 limited slip axle, with 3.73 gearing. Use 75w/140 synthetic. I replaced my seal last year and allowed the fluid to "pack" it. Others will pack the bearing with grease. I didnt in fear of cross contaminating. You can fillthe bearing cavity, seal up the axle and call it good, or for good measure, replace/install everything then park the rear tire in the gutter, allowing the fluid to travel to that area....
